This is a list of historic and current command flags of the Royal Navy.

Rank flags to denote the commander-in-chief of the English fleet and later Royal Navy were used from as early as 1189. Coloured squadrons of the Royal Navy were established during the Elizabethan era to subdivide the fleet into three squadrons or more. There were three classes of admirals and later a fourth that were differentiated by using coloured flags red, white and blue.^[1]

• 
  Arms of the Kingdom of England to 1198.
• 
  Arms of the Kingdom of England to 1199–1340.
• 
  Arms of the Kingdom of France.

The earliest known usage of a command flag being used to denote the Commander-in-Chief of the English Fleet was during the reign of Richard I in 1189 that depicted a single gold lion on a red background.^[2] In 1198 it was changed to include three red lions against a red background which are still part of the royal coat arms of England till today.^[2] In January 1340 Edward III proclaimed himself King of France and adopted the arms of France then displaying (multiple fleur-de-lis or azure semi-of-fleur-de-lis) in the upper left and the lower right cantons with the arms of England in the upper right and lower left cantons to create a new Royal Standard.^[2] In 1411 Henry IV altered the French element of the standard to include just three fleur-de-lis.^[2]

In June 1340 Edward III commanded the English fleet at the Battle of Sluys where the king's standard was flown at top of the main masthead. This positioning of the only command flag used during that battle was later reserved for use by the monarch or his deputy commander the Lord Admiral.^[2] In 1495 Henry VII authorized the use of his standard during the expeditions of John Cabot. In 1530 Henry VIII instructed Sir Thomas Audley to create a set of instructions that made clear which command flags were to be flown on board ships and by whom (at this time a single command flag was to be used at the top of the masthead). Audley produced the book of instructions called the Book of Orders for the War by Sea and by Land.^[3][4] Between 1545 and 1547 Lord Lisle under instructions from the King altered Audley's instructions this time to denote three squadron commanders as follows.^[5]

The Lord Admiral shall fly the royal standard at the top of the main masthead and the flag of the cross of Saint George at the top of fore (front) masthead displaying two flags every ship in his squadron the captains were to fly a single Saint Georges flag at the top of the main masthead. The Admiral of the Van or (Vice-Admiral) of the front squadron flew two flags of Saint George one at the top of the main masthead center and the other at the top of the front masthead. All captains of ships in his squadron fly a single cross of Saint George at the top of the fore masthead. The Admiral of the Wyng or (Rear-Admiral) of the rear squadron to display two flags of Saint George one at the top of the main masthead center and the other at the top of the mizzenmast or rear mast head. All captains of ships in his squadron fly a single cross of Saint George at the top of the rear masthead.

From 1545, the Council of the Marine debated that it was necessary to identify which ship carried an admiral, and this achieved by flying the St. George Cross flag from the mizzen mast. When English fleets became larger, flags started to become used as signals of a squadron to which a particular ship belonged; this was initially done by flying a flag on either the foremast, or the mizzen mast or the top mast. The royal standards were used to identify which senior naval commander was on board. By 1588, only the royal arms, the national flags, and the squadron ensigns (by this time plain red, blue and white flags, for the first, second and third squadrons respectively) were used.^[6]

The Navy Royal inaugurated squadron colours during the reign of Elizabeth I (1558-1603) to subdivide the English fleet into three squadrons. There were three classes of admirals and differentiated by using coloured flags.^[7] In 1620 the official flag ranks of admiral, vice admiral, and rear admiral were legally established that arose directly out of the organisation of the fleet into three parts.^[8]

  Command flag of Richard I as Commander in Chief English Fleet in 1189.

The Admiralty anchor flag first appears as a badge in the early 16th century that was mainly used for decorative purposes. The first time a specific flag was designed and flown was for the Lord Admiral of England Sir Lord Howard of Effingham on HMS Ark Royal as Commander-in-Chief of the English Fleet against the Spanish Armada in 1588. It would not be flown again until 1623 when the Lord Admiral the Duke of Buckingham was given an ensign depicting the admiralty anchor.^[2] However it was rarely used for as a command flag for naval operations instead it became the main flag to signify the Admiralty and Marine Affairs Office.

Their immediate subordinates were Thomas Howard, 1st Earl of Suffolk as Vice Admiral of the Fleet and Sir Walter Raleigh as Rear Admiral of the Fleet. They both commanded a squadron and had a vice admiral (second-in-command) and rear admiral (third-in-command) subordinate to them.

Perrin (1922) does note indicate what flag rank these officers were suffice to say there was no admiral of the red in existence until 1805 so we must assume they were vice-admirals.

From 1628 following the creation of the Board of Admiralty and the post of Lord Admiral placed in abeyance the Royal Standard was not used thereafter as the command flag at sea for a Commander-in-Chief of the English Navy.

Following the execution of Charles I of England, the royal standard was replaced by the Commonwealth standard, with the cross and harp this was used as the main command flag for the General's at Sea together with a designated squadron ensign.^[2]

• 
  Flag of the commonwealth flown at the main mast.

  Red ensign flown at the aft mast.

• 
  Red ensign flown at the aft mast.

  Plain white flag flown at the main mast.
• 
  White ensign flown at the aft mast.

Note: During this period the rest of the commonwealth fleet was divided into nine formations each assigned red, white and blue colours that included plain flags and the coloured ensigns. At the Restoration

In 1660 the all previous command flags used during the commonwealth period were changed back to what they were from 1627 to 1649. However during this period we see the introduction of the post of Commodore being initially recognized (though not formally) in November 1674. The Board of Admiralty on the advice of the Navy Board approved the use of the first pendant (later known as a pennant) to denote the command flag of senior officer in charge of a small squadron under a captain as a plain red pendant. The use of the flag became known as The Distinction Pendant to denote a Commander-in-Chief who did not hold flag rank. In January 1684 a proposal was put forward to distinguish two senior officers in a small squadron based on their age difference and relevant naval experience it recommended the issuing of two pendants a plain red of distinction with a white cross for the officer of distinction and a smaller plain red for the officer of the ordinary this separating of two types of commodores would evolve into those of the first class and second class. In 1734 the title of commodore was formally approved by an Order in Council. In 1806 the temporary flag rank of Commodore was to be distinguished by a 'Broad Plain Pennant' of either red, white or blue. The ordinary commodore commanding a ship themselves would have the same coloured pennants but with a single large white ball near the staff.^[2] Below for illustrative purpose is what they might have looked like.

Note: Perrin (1922) in his descriptions of admirals command flags does not mention the commodore ordinary of the white squadrons pendant in relation to the 1805 changes thus we must assume that as the Red and Blue squadrons officers were changed to large white balls; the white squadron had to have a large red ball.

• 
  Commodore distinction red squadron 1674 .
• 
  Commodore distinction white squadron 1674
• 
  Commodore distinction pendant 1684.
